YÜKSEK ENFLASYON ENFLASYON BELİRSİZLİĞİNİ ARTIRIYOR MU?
Bu çalışmada, Türkiye ekonomisinin 1987:01-2005:06 döneminde enflasyon ve enflasyon belirsizliği arasındaki ilişki incelenmiştir. Enflasyon belirsizliğinin ölçülmesinde EGARCH yöntemi kullanılmıştır. Hsiao ve Granger nedensellik testlerine göre çift yönlü nedensellik ilişkisi olmasına rağmen, Granger nedensellik testine göre enflasyon belirsizliğinden enflasyona doğru olan nedenselliğin işareti istatistiksel olarak anlamlı olmadığı görülmektedir. VAR analizi sonuçlarına göre de tek yönlü bir nedensellik ilişkisi mevcut ve bu ilişkinin yönü de enflasyondan enflasyon belirsizliğine doğrudur. Kısaca enflasyonun enflasyon belirsizliği üzerinde güçlü bir etkiye sahip olduğu görülmektedir. Granger nedensellik testi ve VAR analizine dayanarak elde edilen sonuçlar, incelenilen bu dönemde, Friedman-Ball hipotezini desteklemektedir
